The 7i90 is designed to be programmed from an epp parport, and I don't
believe it can be programmed again once an spi interface has been put in
it with out doing some jumper moving to reset it to parport drive before
it can be reprogrammed again. Its explained in the docs for it. It is

No, once you have an spi bitfile loaded you
can mesaflash over spi, without going back
to parallel port or jtag. Your original mesaflash
line will work once you have an spi bitfile in
there.

You have to get an spi bitfile loaded before you can use spi.

You have to get an spi bitfile loaded before you can use spi. I rigged up jtag
with openocd on my Rpi3b+ to bootstrap the 7i90.
